Forking creates new Node.js processes that run separate instances of the V8 engine, ideal for CPU-intensive tasks that would block the main event loop. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented process forking in Node.js applications throughout my 11 years of backend development. The most effective approach is using the fork method from the child_process module to spawn Node.js child processes with built-in IPC communication. This method enables message passing between parent and child processes while maintaining process isolation.
